XV. T. FRY, OF PHILADELPHIA, PENNSYLVANIA.

INIPROVENIENTIN FLASKS AND BOTTLES.

Specification forming part of Letters Patent No. 40.338 dated October 20, 1863.

To all whom t may concern,.-

Be it known that I, WILLIAM T. FRY, of Philadelphia, Pennsylvania., have invented an Improvement in the Necks ot' Bottles and Caps for the Same; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to Athe accompanying drawings, and to theletters of reference marked thereon.

My invention relates to an improvement in that class of bottles or fiasks to the necks of which are cemented screw-caps of metal for the reception ot screw Stoppers containing cork or other elastic material for closing the mouth of the bottle, my improvement, which is fully described hereinafter, being such as to prevent the contents of the bottle from gaining access to and acting injuriously on the cement by which the screwcap is secured to the neck.

In order to enable others to make and apply my invention, I will now proceed to describe the manner of constructing the same.

On reference Vto the accompanying drawings, which form a part of this specification, Figure l is a vertical section of part of a flask illustrating my improved neck and cap 5 Fig. 2, a plan view of Fig. l, and Fig. 3 represents a section ofthe ordinary stopper or mouth for flasks.

In order that my invention may be readily understood, I will, in the first instance, proceed t0 describe the usual manner of forming the neck of an ordinary bottle or ask and cap for the reception ot a screw-stoppe'r, as illustrated in F-ig. 3, where A represents the neck ofa ask, B a portion of the leather covering, and C the metal cap for receiving the screw-stopper Il. This cap consists of a metal ferrule with screw-threads on the outside, and on the top a flange, a', the ferrule, as well as its iiange, being cemented to the neck of the flask. A stopper, E', is screwed onto the cap C', the internal elastic material, D', bearing on the top of the iiange a', so that the cement at x rv must be constantly exposed to the contents of the flask;

Now, it is well known to those familiar with the manufacture and sale of this class of bottles or asks that there is great difficulty in maintaining the cap C tight on the neck,owing to the action of the contents of the bottle on the cement. rIhe .diflculty of obtaining a proper cement, capable of resisting the fluid contained in the bottle, is also well known. rIhus a cement which would resist the action of water would not resist that of alcohol, and one that would resist the action of alcohol would not resist that of essential oils. In order to obviate this difficulty, I construct the mouth of the vessel in the manner seen in Fi l, the metal cap C being cemented to the neck ofthe vessel, as usual; .but the flange a of the cap, instead of being cemented tothe top otthe flask, is cemented to a shoulder, y, formed on the neck, while the latter is reduced in diameter and continued upward, as seen at by Above the fiange a ofthe cap, and against this continuation of the neck, bears the cork or other elastic material, D, which is secured to the inside of the stopper E, the latter being screwed onto the cap C.

It will be evident that this simple improvement effectually prevents the contents of the flask from gaining access to and loosening the cement, by means of' which the cap is secured to the neck of the vessel. l

It will also be evidentthattheimprovement is applicable to portable flasks for containing liquors, to inkstands, vessels for the toilettable, druggists bottles, Ste., and that both cap and stopper Inay be made of vulcanized rubber or other hard material.

I claim as my invention and desire to secure by Letters Iatent-` rlhe neck A of the bottle and the cap C, both being constructed, adapted, and cc- Inented to each other, and arranged for the reception of the screw-cap E, all substantially as set forth.

In testimony whereof Ihave signed my name to this specification inthe presence of two subscribing witnesses.

WM. THO. FRY.
